1. Go to Shellshock Live in your Library (does not need to be installed).
2. Click Support on the right hand side. It's near the bottom of the links section.
3. Answer the questions and make a refund request.

Note: This is a request. Valve does not have to approve it. They won't if the game's been owned by you for longer than two weeks or you have more than 2 hours of game play.
